Norton Hotspot Privacy 1.1.3 is discontinured as of 10 2014: How do I delete it?

Since Norton Hotspot Privacy 1.1.3 has been discontinued as of October 2014: How do I delete it?  I did not know this when I downloaded it from iTunes.  It should be taken down from iTunes App Store if it is no longer a working App.  Now that I have a non working app on my iPhone4 taking up space, I'd like to delete it.  I've taken it off of my purchase apps on iTunes however the app is still on my phone.  Anyone know how to help a newbie take nonworking apps off an iPhone4 still running OS 7?  Thanks
